21020231 divided by 923 
We want to divide 21020231 by 923.

On to step 1:
2 divided by 923 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 923

On to step 2:
When dividing 21 by 923, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 923

Moving on to step 3:
210 divided by 923 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 210, we get 210.
Include the next digit (2) from the dividend after 210, then repeat: 2102 / 923

Advancing to step 4:
If we divide 2102 by 923, we get 2 and a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1846 from 2102 and we're left with 256.
Bring next digit (0) of the dividend behind the 256 and repeat the process: 2560 / 923

Moving on to step 5:
923 goes into 2560 2 times with a remainder of 714.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 1846 from 2560, we get 714.
Include the next digit (2) from the dividend after 714, then repeat: 7142 / 923

Advancing to step 6:
The number 923 fits into 7142 7 times, leaving a remainder of 681.
Use 7 as the next digit of our solution. 
Result so far: 227.0
Deduct 6461 from 7142 and we're left with 681.
Take the next digit (3) from the dividend and append it to 681, then repeat: 6813 / 923

Moving on to step 7:
923 goes into 6813 7 times with a remainder of 352.
Record the quotient 7 as the next digit in the result. 
Result so far: 2277.0
Subtracting 6461 from 6813 leaves us with 352.
Take the next digit (1) from the dividend and append it to 352, then repeat: 3521 / 923

Moving on to step 8:
923 can be fit into 3521 3 times, resulting in a remainder of 752.
The number 3 becomes the next digit in our result. 
Result so far: 22773.0
If we subtract 2769 from 3521, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 9:
923 goes into 7520 8 times with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 22773.8
If we subtract 7384 from 7520, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
If we divide 1360 by 923, we get 1 and a remainder of 437.
Write down 1 as next digit of the result. 
Result so far: 22773.81
If we subtract 923 from 1360, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 11:
The number 923 fits into 4370 4 times, leaving a remainder of 678.
Use 4 as the next digit of our solution. 
Result so far: 22773.814
Subtracting 3692 from 4370 leaves us with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Advancing to step 12:
If we divide 6780 by 923, we get 7 and a remainder of 319.
The next digit of our result is 7. 
Result so far: 22773.8147
If we subtract 6461 from 6780, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 13:
3190 divided by 923 is 3 with a remainder of 421.
Record the quotient 3 as the next digit in the result. 
Result so far: 22773.81473
Deduct 2769 from 3190 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 14:
If we divide 4210 by 923, we get 4 and a remainder of 518.
Record the quotient 4 as the next digit in the result. 
Result so far: 22773.814734
Subtract 3692 from 4210 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 15:
If we divide 5180 by 923, we get 5 and a remainder of 565.
The next digit of our result is 5. 
Result so far: 22773.8147345
If we subtract 4615 from 5180, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 16:
When dividing 5650 by 923, we get 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 22773.81473456
The remainder is 112 after subtracting 5538 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 22773.81473456 with a balance of 1.12e-07.
